你如果用的是政府的租約模板，上麵有棄約的條款，像這樣的。。。

Tenant shall give Landlord notice of any anticipated extended absence of Tenant from the Dwelling Unit in
excess of seven days. During such absence of Tenant, Landlord may enter the Dwelling Unit at times
reasonably necessary to protect the Dwelling Unit. If Tenant fails to give such notice, Landlord may recover
from Tenant any actual damages sustained, and shall have all other rights provided in the ?RLTA. If Landlord
cannot determine whether Tenant has abandoned the Dwelling Unit, Landlord may serve written notice on
Tenant requiring Tenant to give Landlord written notice within seven days that Tenant intends to remain in
occupancy of the Dwelling Unit. If by the end of such seven-day period Landlord has not received such notice
or has otherwise determined that Tenant has abandoned the Dwelling Unit, the Dwelling Unit shall be
presumed abandoned and this Lease shall be terminated as of such date.
